In agricultural production, meteorological factors are the main factors affecting the growth and production of crops, and most of the loss of meteorological disasters is caused by insufficient preparation for meteorological development and failure to take timely preventive measures. Therefore, to master the initiative, we need to take the initiative to pay attention to meteorological changes, using modern technology to strengthen the detection and analysis of agricultural meteorology. The hand-held wind speed and direction meter is a small-scale agro-meteorological instrument for measuring wind direction and wind speed. The application of this type of instrument makes weather monitoring easier and promotes the in-depth development of meteorological services for agriculture. In various regions of China, unique climatic conditions have given birth to different crops, which have made the high-quality development of various characteristic industries, but also affected by climatic conditions. The meteorological climate has sometimes turned into a "devil", all kinds of heavy rain, hail, Natural disasters such as freezing damage have come to the fore, destroying various crops and causing serious disaster losses. Therefore, in the face of unpredictable meteorological changes, we only rely on modern technology to strengthen the detection and data collection and analysis of various meteorological environments, then it is possible to become passive and take the initiative to better use meteorology for agricultural production services. In this process, hand-held wind speed and other weather instruments are reliable helpers for accurate and real-time understanding of the meteorological environment. Handheld wind speed and direction instrument and other meteorological instruments are easy to operate, easy to carry, fast and accurate measurement results, not only able to collect and save data, but also wirelessly transmit data, remotely view and download data, as long as there is a network, you can get it in time. Weather data to understand meteorological changes. Therefore, the relevant departments can use these meteorological instruments to better grasp the changes in the meteorological environment in the monitoring area, realize the real-time exchange of information and the rapid transmission of meteorological forecast and early warning information, and guide farmers to take timely measures to avoid losses when encountering meteorological disasters. The support work provides strong support.
